Two main types of data transmission media?

Answer 1

Here, we have two types of transmission media:

1. Guided media transmission


2.unguided media transmission


in guided media,there are wires or cables, whereas in unguided media,different-different waves are used.


1. Guided media transmission
a.) co-axial cables
b.) twisted pair cables
c.) optical fiber cables


2.) unguided media transmission
a.) infrared rays transmission
b.) radio transmission
c.) microwave transmission
d.) satellite communication transmission

Answer 2

There are 2 basic categories of Transmission Media:

- Guided

- Unguided

Guided Media covered

§ Twisted Pair Cables

· Unshielded, Shielded

§ Coaxial Cables

§ Optical Fiber Cables

- Twisted pair cables have been used for connecting telephones to Local Exchanges ever since telephones were invented, the size and thickness have changed but they are basically the same as they were in the early twentieth century.

- TP cable consists of two conductors (normally copper), each with its own plastic insulation, twisted together

- One of the key problems in transmitting signals from one device to another is the electrical "noise" or Radio Frequency Interference (RFI) that penetrates the cable and gets mixed with the useful data or signal.

- The longer the cable, the more likely the RFI.

- RFI, radio frequency waves that travel through the air, are intentionally and unintentionally generated by a wide variety of electrical equipment.

These include TVs and radios, electrical motors, elevators, photocopiers, microwave ovens, fluorescent lights, all broadcast antennas, and all the communications equipment and computers themselves

- The first line of defense against RFI is to shield the cable with a conductive material that has been electrically grounded.

- To overcome such limitations, equipment designers have turned to a technique of transmitting computer signal called the DIFFERENTIAL system.

Categories of Twisted pairs

- STP (Shielded Twisted Pair)

- UTP (Unshielded Twisted Pair)

Answer 3

" Quote Transmission media is a pathway that carries the information from sender to receiver. We use different types of cables or waves to transmit data. Data is transmitted normally through electrical or electromagnetic signals. ... Transmission media is also called Communication channel."

Answer 4

twisted pair is best example of transmission media
